The Skimmi is in a sunny location, but it isn't charging

The fix

Step by step.

This can occur when the battery is full so that the skimmer runs on solar power instead of battery. When the sunlight becomes weaker, the battery will start to power the skimmer again and will continue charging.

  1. Ensure the Skimmi is exposed to direct sunlight to let the battery recharge. Cold weather and cloudy skies may impact the charging ability.

  2. If the SKIMMI won’t charge, please open the app and note the charging strength.

If the charging strength is below 5 Watts, please check for possible limescale residue accumulation on top of the solar panel. In such a case, please gently clean the residue off using diluted citric acid or vinegar.

If the charging strength is above 5 Watts, but the SKIMMI won't accumulate charge, it may indicate a faulty battery.

Important: The robot is a solar-powered model. Sufficient solar power and direct sunlight are required for proper charging and operation.
